This is a waste of a buck

When I open this app, it goes to the home page, but there is nothing on it. When I type in a blood sugar number, it doesnt move on to the graph. Why cant I go back from the email program? I have to quit and start over. Where is an email address for the developer?? When I click on the link in iTunes it goes to a web site forum. Im a newbe. Help. Thx.
